FUEL-CEABiGlE-DILUTING DEVICE.

Application filed December 16, 1924. Serial lilo. 756,319.

This invention relates to an improved fuel charge diluting device forinternal combos-- eilicioncy of the engine, but also to reduce.

the formation of carbon in the engine cylinders.

v The Invention seeks, as a further ob ect, to

provide a device which may be readily ii -4 stalled and'which will becontrolled in uru-,

son with the throttle valve of the engine carburetor; H

And the invention seeks, as a still further ohject, to provide a'deviceconstructed in such manner as to facilitate the manufacture of thedevice.

Other and incidental objects will appear hereinafter.

in the accompanying drawings:

Figure l is a plan view showing my i1nproved device installed between aconve t? tional carburetor and engine intake inanifold.

Figure 2 is a vertical sectional view taken medially through the device.3 Figure 3 is a transverse sectional view on the line 3-3 oi Figure 2,looking in the direction indicated by the arrows.-

Figure i is a fragmentary horizontal seotiona view on the line 5% ofFigure 2, looking in the direction indicated by the arrows.

lln carrying the invention into efl'echd employ a body block which, asshown in Figure l of the drawings, is shaped to fit between theconfronting flanges 11 and 12 of an engine intake manifold 13 andcarburetor i l. Suitable gaskets 15 are disposed be tween the parts andextending through said flanges and through the block are bolts 16clamping the block in position. The mani told 13 and carburetor 1d are,of course, conventionally illustrated. However, it is desired to notethat the carburetor includes the usual throttle valve having a 5mm 17.,to which is fixed a lever 18, and. engaged with the free end of saidlever is the customary control. rod 1%, the adjacent end fitting in saidopening 7 of which is bentdownwardly, in the usual manner to' form a'terminal extending through the lever. 1

Formed in the block-10 is a central opening 20, stepped adjacent therear side of t the block to define an inwardly directed an-Q nularflange 21, and snugly but removably said flange terminating flush withthe rear face of the block, At the lower side of the opening 20 is, asparticularly shown in Figure 2, a transverse locking rib 23 while thecore-1s formed with a groove accoinrnodatlng said rib sothat the core isthus locked against rotation. At is upper side, the core is cutawaythroughout substantially half the circumference thereof to produce aradial flange 24 snugly fitting in position, a semi-circular passage 25is defined between said flange and the flange 21 of the block hitegrallyformed on the core is a spider comprising a air of forwardly convergingarms 26 which, at their rear' is a core or ring 22 re duce'd near itsrear edge to snugly fit through 7o 7 the opening 20 oi the block 10 sothat when the core is in ends, are united'with the core at its innercircumference while, at their forward endsp said arms are merged andcontinued to form a forwardly directed cylindrical nozzle 27. Formedthrough the arms to communicate with the ends of the passage 25 arepassages 28 opening into said nozzle, Mounted upon the spider is adisc-shaped, spreader 29 hav ing a stem 39 extending through the noz-vale and screwed through the crotch between the arms 26. lhe spreader isprovided with a cupped rear face for deflecting radially in a thinsheet, the vapors emerging from the nozzle and, as will be perceived,the spreader may be rotatably adjusted for p0- sitioning the spreaderwith respectto the forward end ol the nozzle.

Formed through the block 10 above the openin 20 therein and at a rightangle to the axis 0' said. opening, is a passage 31 con nected mediallywith the passage 25 by a port 32 and opening into the passage 31 nearone end thereof is a downwardly extending passage 33, the lower end ofwhich is open to the atmosphere. Detachably connected with the adjacentend of the passage 31 is a moisture supply pipe 3d leading from theradiawith the radiator in'any approved manner and adjustably butpreferably communicates neck of the radiator so that steam will besupplied through said pipe to the passage 31. Slidable in the outer endof said passage is a piston valve 35 having a stem 36 fixed to said stemis an angle plate 37 secured by nuts 38 screwed on the stem. The plate37 is disposed to overhang the block 10, and pivotally connected to thefree end of said plate is a link 39, the free end of which is aperturedto receive the terminal at the adjacent end of the control rod 18.

' ing a steam will then As Wlll now be'seen in view of the foregoingdescription, to the position shown in Figure 1, for closing the throttlevalve of the carburetor 14, the valve will be shifted across the port 32for closing said port. On the contrary, when the lever is swungforopening the throttle valve, the valve 35 will, as the openmovement ofthe throttle valve proceeds, be gradually shifted outwardly to uncoverthe port 32, so that air and steam will be drawn in through the passage33 and pipe 34 into the passage 31 to become mingled in the latterpassage. The mingled air and be drawn through the port 32 and throughthe passages 25 and 28 as well as through the nozzle 27 to strike thespreader 29 and be spread out in a thin sheet thereby. Coincidently,the. carburetted fuel from the carburetor will be drawn through thecentral opening of the core 22 about the nozzle andspreader so that themingled fresh air and steam will be injected into the carburetted fuelto form a diluted fuel mixture for delivery through the manifold 13 tothe engine.

Having thus described the invention, what I claim is:

1. A diluting device including a body block having an inlet passagecommunicating with the atmosphere, and a core carried by the block andprovided with an opening for the fiow of carburetted fuel as well aswith a nozzle disposed opposite said opening and connected with saidinlet passage.

2. A diluting device including a body block having an inlet passagecommunicating with the atmosphere, a core carriedby the block andprovided with an opening for the flow of carburetted fuel as well .aswith a nozzle disposedopposite said opening and connected with saidinlet passage, and a with the filler when the lever 18 is swung corebeing rovided with a spreader disposedat the discharge end of v thenozzle.

3. A diluting device including a body block having an inlet passa ecommunicating with the atmosphere, anrf a separate core carried by thebody opening for the flow of carburetted fuel, the core having a atingwith the block to define a passage connecting the nozzle with said inletpassage.

4. A diluting device including a body block having an inlet passagecommunicating with the atmosphere, a separate ringshaped core carried bythe body and provided with a spider terminating in a discharge nozzle,the spider being formed with a passage leading'to said nozzle, and acore cooperating with the block to define a passage connecting saidpassage of the spider with said inlet passage. g

5. A. diluting device including. a body block having an inlet passagecommunicating with the atmosphere, a core carried by the body andprovided with a spider terdischarge nozzle and cooper-- minating in adischarge nozzle, the spider being formed with a passage leading to saidnozzle and the core cooperating with the block to define a passageconnecting said passage of the spider with said inlet passage, and aspreader disposed opposite the nozzle and having a stem extendingthrough the nozzle andadjustable upon the spider.

6. A diluting device including, a body block having an inlet passagecommunicating with the atmosphere and provided with an opening as wellas ing into said opening, and a core having integral forwardlyconverging spider arms merging at their forward ends and provided with adischarge nozzle, one of said arms being formed with a passage leadingto the nozzle andv the core being cut away to fit through said flange aswell as to produce a flange cooperating with the block and with saidfirst mentioned flange to define a passage connecting the passage. ofsaid arm with said inlet passage.

7 A diluting device including a body block having a core provided withan openingfor the passage of carbureted fuel, the portion extendingforwardly from the core and formed with-a passage communicating with theatmosphere through the block and terminating in a nozzle disposedopposite said opening at .the forward end of said portion.

In testimony whereof I afiix my signature.
